Abstract
A light-emitting device is capable of oscillating in a convex-whispering gallery mode. The lighting-emitting device includes a PIN-type semiconductor including a p-type distributed Bragg reflector, an active region and an n-type distributed Bragg reflector formed on a substrate by an epitaxial growth, wherein the PIN-type semiconductor having a hole with a predetermined diameter formed thereon, and an electrode connected to a region around the hole for applying a current to the hole. Further disclosed are a method for manufacturing the light-emitting device and an array of light-emitting devices.
